Maybe it's in the thought process.
The thrust side as I was taught, is always in the direction of rotation. So on the triples, that's the exhaust side. Reversion the cylinders puts the thrust side in the intake side now, so it would be cooler.

I will disagree on that one. The hot side will always be the exhaust side The offset piston pin also reduces thrust loading on the piston. |

Well no, we do agree, the thrust side runs hotter than the non thrust side. All I said was, add the exhaust heat to the hotter thrust side by reversing the cylinders, then you could have a problem. |

It's easy to imagine, when the piston is on the firing stroke, going downwards under it's max load, what angle would the rod be at. For a 'forwards' rotating crank, the rod will be leaning 'backwards', it's that rod angle that puts a rearwards load on the piston. So, all conventional 'forward' rotating engines have a rear thrust face, which is the cooler intake side, which on a piston port motor, happily also has a fuel/oil mist directly onto that piston skirt. |

Then we can just disagree, it's all good...........

+1 Shall we say anti-thrust is the exhaust side on our Kows? Everybody then gets a trophy!

Yup, fully agree, can tear up a piston, IF the thing isn't built/tuned correctly, and that goes for pistons aimed at the front, and/or rear. I've never had failure issues with any of the engines I posted above, and I have worked on all but one of them personally, but then, I built and tuned them correctly, comes from paying attention, and doing that work for 4 plus decades. Have seen others go way past sensible, and make just about anything else turn ti instant meltdown, no matter where the pistons were aimed. |
